The more you read about the 'situation', the more you understand that Diggs was not likely the #######. There's a lot to unpack and I'm sure Diggs wasn't totally innocent, but his attitude there seemed to be the same it was here...he was just surrounded with people who didn't have an interest in improving (Cousins) and some who took issue that he did not share their religious beliefs (Cousins).
Vikings gave Cousins a stupid extension for some reason so they had to ship one of them out. They chose...poorly.
Allen is routinely touted as being 'coachable' and affable. So when Diggs was over telling Allen what he did well, what he did wrong, etc, etc...Allen is like "Hell yeah" where Cousins takes it as an insult.
